At about 8:38 PM on Thursday April 28, 2016, officers assigned to the Youth Violence Strike Force made an onsite firearm arrest in the area of 5 Trull Street in Dorchester. The officers were on directed patrol in the area in response to numerous firearm related incidents in recent weeks. Officers observed a 16 year old juvenile from Dorchester, attempting to avoid detection while standing in a clearly marked no trespassing area behind a house. As the officers approached to speak with the suspect, he discarded a loaded Taurus Ultra Lite .45 caliber revolver which was quickly recovered. The suspect was then placed in custody without incident. The suspect will appear in Dorchester Juvenile Court on charges of Delinquent to Wit: Unlawful Possession of a Firearm, Unlawful Possession of Ammunition and Trespassing.
